KellyS, I am curious about nutritional yeast. I know what it is. I have seen it in a few delicious looking recipes added in a place of cheese. I am wondering, if it really gives you that parmesan like flavor?I can just pipe in a little here if that's okay! Nutritional yeast is flaky, it is a "deactivated" form of a certain yeast. It has a ton of B-vitamins in it, and many folks used it to make "cheeses", sauces, or they'll sprinkle it right on salads and popcorn. Bettylacy will surely have some more info, too!
PS = Bragg's is a pretty popular brand, too. =)
Have you tested it?
